From 53e78539de11fa4f52348fa711d723742802a479 Mon Sep 17 00:00:00 2001 From: "henryc.chen" Date: Mon, 25 Apr 2016 15:53:29 +0800 Subject: soc/mediatek/mt8173: mt6391: vcore sleep voltage should be 0.7V Vcore voltage should be 0.7V during system suspend. Because data sheet of mt6391 was not correct, need to config to 0x0 instead of 0x1.
